Dont have a solution but i have a 3.1 and its doing the same thing. we checked fuel press. and its fine but some one told me that its the fuel pump because if you drive on a half a tank of gas or less the fuel pump is not cooling off properly so it shuts eng. off. cause fuel pump is going bad and it will not show any codes if tested. so i am replacing the fuel pump $260 hopefully this will solve the problem but try driving with full tank of gass it should not do it as often but after about 10 min car should start after it dies.
My Pontiac Grand Prix is also a 99, it has 216,+ thousand miles on it, it runs great, idles good, I need to replace the oxygen sensor tho as it shuts off on me while driving or sometimes coming to a stop. You might try checking the fuel filter and pump as well.
check to see if you have a faulty fuel pump relay. Mine would work then not work.It boggled 3 different meachanics,.the place I traded it in at told me that was the problem,.it's relativly a cheap part depending on vehicle
check all fuses for turn signal and brake lights.change fuel filter . first. do a little tune up change spark plugs and wires . if changing fuel filter dont help. have fuel pressure check first before buying a new fuel pump .they run after taxes 400.00 dollars. your fuel pressure should be 41 to 47 psi. replace fuel pump relay also.
is this a supper cahrged grand prix if so check fuel pump resistor located behind right front head light or on fire wall its made of white ceramic has to wires going to it jump the two wire on the connection going to it if it runs longer then 15 min then replace resiustor.
